Bystander CPR is associated with higher survival rates for out-of-hospital cardiac arrest, but its association is weakest among Black individuals and women, according to a recent study.
Researchers analyzed 623,342 "nontraumatic out-of-hospital cardiac arrests" from 2013 to 2022 in the U.S. as reported to the Cardiac Arrest Registry to Enhance Survival registry. They examined the association between survival outcomes and sex, race and ethnicity of the patients.
The association of bystander CPR and survival was smallest for Black women and largest for white men, according to a study published Aug. 7 on the American Heart Association's website.
Of those studied, 14.9% of white men who received bystander CPR survived to discharge, compared to 8.4% of Black women.
The survival of white women followed white men at 11.2%, which was followed by Black men at 10.1%.
Whether these differences are because of differences in the quality of the bystander CPR or rates of unassisted versus dispatcher-assisted CPR deserves further study, the researchers wrote. Of those studied, 9.3% survived to hospital discharge.
